“Oh come on, really? Do I have to?” I whined to my wife Dawn.

“Yes, I can’t make it and someone needs to make sure she’s not buying crap.” she replied.

My step-daughter Hannah was in her second year of school about 1.5 hours away. We got her an apartment close to campus so she wasn’t on the dining plan. She had a medical scare over the summer and needed to lose some weight and eat better. Hannah was a big girl, about 5’8 and 250lbs and only ate crap which didn’t help. So now, we were trying some new stuff, more Keto based to help her eat better and lose weight while trying to still make sure she liked it and would actually eat it.

So, the deal was we would pay for her food for the month based on a pre-ordained menu and ingredient list that she had approved. Which meant that she either had to come home every month to do shopping, or we had to go down there. Unfortunately, this month she was unable to come up due to events at school and Dawn was unable to go down due to work committments. Which means it was now my “turn” to go down there and supervise her shopping. Dawn knew that left to her own devices she would just buy a lot of crap food and go back to her old habits.

I mean, it could be worse. It was only a 1.5 hour drive, an hour or so shopping and then I could head back. But there’s always a monkey wrench, right? I was planning on leaving around noon and being back before dinner but I got stuck doing some installations and it was about 6pm before I could even leave. That meant that either I don’t get back until late, or I crash at Hannahs apartment and leave in the morning.

Luckily, even though it was a 2 bedroom apartment, she was only paying for 1 bedroom and the shared common area and another student was supposed to be renting the other room so it was just Hannah at the moment. The other room was locked so the only place for me to sleep was the sofa. I considered bringing an airbed but figured the sofa would be good enough.

I packed an overnight bag and got on the road around 6:15 and pulled up to Hannahs’s apartment around 7:35pm (Hey, I made good time!) She came bounding out the door to my car as soon as I pulled up.

“OK come on let’s go!” she said. “The stores close at 9 so we have to hurry.”

“Nice to see you too, how’s everything going?” I said.

“Oh sorry, Hi Mark, thanks for coming down.” she laughed. “Now let’s go!”

I pulled right back out and headed to the Walmart 15 minutes down the road. We did our shopping and Hannah did a good job of picking out the stuff she was supposed to and we finally headed back to her apartment. It took another 10 minutes to unpack everything and put it away before I finally plopped down on the couch.

“We done now?” I asked. “It’s hot and I want to throw on my sleep shorts.”

“Yeah we’re good now. I’m gonna go sit and do some homework” she replied.

I went through my back until I found my gym shorts and went into her bathroom to put them on before heading back to the couch and sitting down to relax. She was at the kitchen table with a couple of books and a notebook studying something I had no interest in knowing. I took out my laptop and started looking at Facebook and playing some games online for the next hour or so.

Today, Hannah was wearing a t-shirt with a pair of tight, thin sweatshorts. They pulled tight around her pussy and I think her fat ass barely fit in them. I couldn’t help noticing since she sat with one leg up which gave me a straight on view of a little camel toe. Over the course of that hour I kept having to adjust my cock in my shorts because it would get hard every time I got a view of those shorts stretched around her fat cunt. It’s not like I lusted over her at all, she wasn’t all that attractive to me. But I am a guy and she has a pussy which I’m looking right at so yeah, hard on. She was working so I didn’t think she noticed until probably the 5-6 time that had to adjust.

“Why do you keep doing that?” she asked.

“uhh doing what?

“You keep adjusting your shorts.”

“ohh that. It’s a guy thing, girls just don’t understand.” I replied vaguely.

“Well explain it to me then.”

One thing Dawn had taught Hannah was to always ask questions. Sometimes it was really annoying. Like ‘where are you guys now’, or ‘what’s in that box’ ... basically things that had nothing to do with her, or no real value. At least in my opinion. But hey, she did ask so...

“OK you asked.” I said, I figured if I made her uncomfortable that she would stop. “my dick gets hard and I need to change the direction it’s pointing.”

“oh” she replied. Her face getting slightly red. I figured that this would end this line of questioning. “Why is it getting hard?”

Oooof. I wasn’t expecting her to continue this line of questioning but hey, her mom was always honest with her when she asked any type of question so I figured that the more uncomfortable I made her the less questions she would ask and I could get back to mindless Facebook browsing.

“Because when I look up, you’re sitting there with your leg up and those shorts are kinda tight.”

“Oh” was all I got in reply. She didn’t say anything after that so I went back to my computer. Next thing I know she had sat down on the couch next to me.

“So, you were thinking about me and it got you hard?” she asked.

“yeah, I mean I’m a guy, it happens.”

“Is it hard now?”

“uhhh no, why?”

“How can I make it hard?” she asked.

“uhhhh” was all I managed to get out. In the 4+ years that I had known Hannah, she had never been overtly sexual. She didn’t dress up, put on make up, date or anything like that. Matter of fact, I wasn’t even sure she liked guys. My bets were the opposite! As far as I knew she had no experience sexually at all, but it’s not like she talked to me about it. My mind was racing as she scooted closer to me on the couch so our legs were touching.

“It looks like it’s hard now.” she said looking down. “Did I do that?”

I looked down and yup, little Mark was pushing up against my gym shorts which didn’t offer much resistance.

“uh yeah, it seems that it is” I said. “and yeah, you did that”

She swung her leg over me and was suddenly straddling my lap. Her pussy right over my hard cock. She lowered herself and started grinding her pussy on me.

“Mmmmmm yeah that sure is hard.” she moaned.

My shock must have registered with her because she laughed when she saw my face. Hannah had never been overtly sexual at all in the 4 or so years since I had known her. She never dressed up, or did make up, she didn’t date and to be honest, I thought that her preference was for women. Nor had she seemed to be so aggressive which was a surprise.

“I am not totally inexperienced ya know.” she said. “Nate and I fooled around on our road trip last year.”

Nate was her transgender friend and they had taken a 4-5 day road trip last year to visit some friends that were out of state.

“oh I didn’t know” I said stupidly. I still couldn’t believe that Hannah was on top of me, grinding her fat pussy on my crotch.

“Oh yeah, we fooled around the whole time.” she said “I really liked it, he made me feel so good.”

“uhhh”

“Yeah but I want more.” she kept going. “Nate had a toy that we used and it was nice but I need to try the real thing.”

At that point my cock jumped thinking about her and Nate using a toy to satisfy each other.

“Ohhh I felt that.” she exclaimed. “Why did it do that?”

“I, uh, I was thinking about you and uh, Nate using a toy.” I admitted.

She leaned forward so that her huge tits were almost in my face and whispered into my ear:

“I still have it.”

My cock jumped again at this and I groaned audibly this time.

“OK so what now?” I asked.

“Oh well uh, I don’t know.” she answered, looking sheepishly at me. “Honestly I didn’t think I’d get this far.”

With that, I grabbed the bottom of her shirt and lifted it up, pushing her arms up with it.

“Ooooh OK” she exclaimed as I tossed the shirt onto the floor. Hannah didn’t wear a real bra, even though her tits were pretty big she just would wear a sports bra. Today though, she wasn’t wearing any and her big fat titties were there just swinging in my face. I reached out with my tongue and licked her nipple and was rewarded with an “oooooooh”.

I grabbed them both and started kneading them and flicking my thumbs over her nipples. I knew that Dawn had super sensitive nipples so if Hannah was the same this would really get her juices flowing. Fortunately I was right as she started grinding harder on me while moaning as I continued to play with her nipples. She was pushing her tits into my hands so I leaned forward and started sucking on her left nipple and then her right.
